Import stacks into AWS CloudFormation StackSets - AWS CloudFormation

Import stacks into AWS CloudFormation StackSets

A stack import operation can import existing stacks into new or existing StackSets, so that you can migrate existing stacks to a StackSet in one operation.

For self-managed StackSets, the import operation can import stacks in the administrator account or in different target accounts and AWS Regions. For service-managed StackSets, the import operation can import any stack in the same AWS Organizations as the management account.

The following are considerations and limitations when importing stacks into StackSets:

  • The import operation can import up to 10 stacks using inline stack IDs or up to 200 stacks using an Amazon S3 object.

  • The NoEcho property is not supported. Stacks that contain NoEcho won't be imported into new StackSets through StackSet import.

  • Stacks can only belong to one StackSet.

  • You can implement stack tags to the StackSet by specifying tags explicitly as parameters in the stack import operation.

  • A stack's custom parameter overrides aren't affected during the import operation.

  • The StackSets quotas and stack instances apply when importing stacks. For more information about quotas, see Understand CloudFormation quotas.
